IEEE SWISS SSC DISTINGUISHED LECTURE (WEBINAR) / Precision BAW oscillators for low power, high performance applications
We hope all of you are doing well and healthy, and had or have going to have a nice summer break.
Your Swiss Solid State Circuit Society chapter is please to host Danielle Griffith Who is a Fellow Engineer in the Connectivity business unit at Texas Instruments in Dallas.
The video conferencing link will be provided on the day to registred attendees.
The topic of the lecture is : " Precision BAW oscillators for low power, high performance applications "
What's remarkable is the path from the first crystal oscillator was designed approximately 100 years ago, crossing the watchmaking path in the 60's, the quest for further reducing the footprint of electronic did not stop and nowdays BAW oscillators are now a commercial reality.
Please Join at 17:00 PM [CET] mute your headset or microphone.
We make a group picture in the begining for society report.
For the Q&A make sure to have your headset or a proper microphone.

Precision BAW oscillators for low power, high performance applications
The first crystal oscillator was designed approximately 100 years ago, and today there are few electronic devices without at least one crystal oscillator to generate an accurate clock reference. Despite being ubiquitous, crystal oscillators have drawbacks, including cost, large size, degraded frequency stability at temperature extremes, and sensitivity to shock and vibration. In the quest for further reducing the footprint of electronic systems to enable new applications, it is desirable to have a high stability resonator that can be integrated into an SoC, while ideally also reducing some of the drawbacks of crystals. Bulk acoustic wave resonators (BAW) are one type of device that has been suggested for this application, with the first BAW oscillator built 40 years ago. The first prototypes suffered from inaccurate frequency and relatively large size. Since then, many advances have been made, and BAW oscillators are now a commercial reality. This presentation will cover the physics of BAW resonators, including frequency selection and passive temperature compensation, and circuit design considerations, such as oscillator topologies, frequency tunability, jitter reduction, and active temperature compensation. Finally, system level advantages will be presented, including improved security and resistance to tampering.
Danielle Griffith received the B.S.E.E. and M.Eng. degrees from the Massachusetts Institute of Technology. In 2003, she joined Texas Instruments in Dallas, Texas and is a Fellow in the Connectivity business unit. She develops circuits and techniques for reducing cost, power consumption, and circuit board area for low power wireless connectivity products. Her current focus areas are architectures for efficient wireless systems, low power oscillators and MEMS circuitry. She has published >50 papers, most of them in IEEE journals or conferences. She has written a book chapter titled “Synchronization Clocks for Ultra-Low Power Wireless Networks” which was published by Springer as a part of the book “Ultra-Low-Power Short-Range Radios”. Danielle holds 19 issued US patents and has given multiple university and IEEE conference tutorial and workshop sessions. She was a member of the Technical Program Committees for the IEEE RFIC Symposium for conferences years 2014 and 2015, the IEEE International Solid-State Circuits Conference for conference years 2015-2019, and the IEEE VLSI Symposium starting in 2019. She is a senior member of the IEEE, an associate editor of the IEEE Journal of Solid-State Circuits, and an SSCS Distinguished Lecturer.
